Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

A theory is proposed to account for some of the age-related differences reported in measures of Type A or fluid cognition. The central hypothesis in the theory is that increased age in adulthood is associated with a decrease in the speed with which many processing operations can be executed and that this reduction in speed leads to impairments in cognitive functioning because of what are termed the limited time mechanism and the simultaneity mechanism. That is, cognitive performance is degraded when processing is slow because relevant operations cannot be successfully executed (limited time) and because the products of early processing may no longer be available when later processing is complete (simultaneity). Several types of evidence, such as the discovery of considerable shared age-related variance across various measures of speed and large attenuation of the age-related influences on cognitive measures after statistical control of measures of speed, are consistent with this theory.

The processing-speed theory of adult age differences in cognition.

In 1974 an article appeared in Science magazine with the dry-sounding title “Judgment Under Uncertainty: Heuristics and Biases” by a pair of psychologists who were not well known outside their discipline of decision theory. In it Amos Tversky and Daniel Kahneman introduced the world to Prospect Theory, which mapped out how humans actually behave when faced with decisions about gains and losses, in contrast to how economists assumed that people behave. Prospect Theory turned Economics on its head by demonstrating through a series of ingenious experiments that people are much more concerned with losses than they are with gains, and that framing a choice from one perspective or the other will result in decisions that are exactly the opposite of each other, even if the outcomes are monetarily the same. Prospect Theory led cognitive psychology in a new direction that began to uncover other human biases in thinking that are probably not learned but are part of our brain’s wiring.

Referenzmodelle sind ein schon langer bekanntes Hilfsmittel, um die Entwicklung und Anpassung unternehmensindividueller Informationssysteme zu unterstutzen. Fur einige Branchen existieren bereits solche Referenzmodelle; die Verlagsbranche gehort nicht dazu. Mit dem vorliegenden Beitrag wird ein Referenzmodellrahmen fur Medieninformationssysteme und hierauf basierend — gedacht als erster Schritt der Entwicklung eines umfassenden Referenzmodells — ein grobes Strukturmodell des Leistungsprozesses von Buchverlagen prasentiert. In diesem Strukturmodell finden neuere technische Entwicklungen, wie z. B. die Mehrfachverwendung von Inhalten und die Inhalteausgabe auf verschiedenen Distributionskanalen, besondere Berucksichtigung.

Engagement in potentially beneficial activities is assumed to be based partially on perceived costs and benefits. Mental fatigue may be one factor that affects perceived costs. We examined age differences in both chronic and situational mental fatigue, and their relation to task perceptions and engagement levels. Younger (M age = 32.6) and older (M age = 73.1) adults completed questionnaires measuring subjective mental fatigue, physical and mental health, and motivational states, along with several assessments of cognitive ability. In addition, assessments of effort expenditure (systolic blood pressure) and task difficulty were collected during performance of a cognitively demanding memory-scan task. Two components of chronic mental fatigue (CMF) relating to affect and motivation were identified. Although the structure of CMF did not vary with age, CMF was differentially predictive of engagement and appraisal levels across groups. As CMF-Affect levels increased, older adults' task-difficulty appraisals increased more than those of younger adults. In addition, CMF-Affect was positively associated with levels of engagement in the young, but negatively associated in the old as memory load increased. Older adults also exhibited higher levels of situational fatigue than did the young, as evidenced by increased levels of effort expenditure as both time on task and objective demands increased. However, little relationship existed between chronic and situational mental fatigue in either age group. These findings suggest that the affective aspect of CMF is particularly consequential in older adults, with both task appraisals and engagement levels being negatively affected when fatigue is high.

Adult Age Differences in the Effects of Chronic Mental Fatigue on Task-Related Fatigue, Appraisals, and Performance.

In industrialisierten Branchen wie dem Automobilsektor manifestiert sich die Industrialisierung aus Herstellersicht unter anderem in einer zunehmenden unternehmensexternen Spezialisierung. Ziel des Beitrags ist es daher zu untersuchen, ob sich eine solche Industrialisierung auch in der relativ jungen SoftwareBranche beobachten lasst. Diese Untersuchung wurde fur das Wertschopfungssystem um die ERP-Software von SAP auf Basis einer Inhaltsanalyse von Literatur und Experteninterviews durchgefuhrt. Insgesamt konnte ein steigender Grad an unternehmensexterner Spezialisierung v. a. fur die Wertschopfungsaktivitaten des Dienstleistungsgeschafts ermittelt werden, wohingegen Forschung und Produktentwicklung als Kernkompetenzen nahezu vollstandig bei SAP selbst verblieben.
